Bayer MaterialScience has plans to construct a TDI (toluene diisocyanate) plant having production capacity of 300,000 tpa and based on its new gas-phase phosgenation process, in Dormagen. Currently, the company's Dormagen site has a 200, 000 tpa toluene diamine plant which is used a raw material in TDI. Also, it houses a 30, 000 tpa test plant for TDI based on its gas-phase phosgenation process.
Further, the company is looking to shut its 125, 000 tpa TDI unit at Brunsbüttel site and scale up the site's 160, 000 tpa MDI (methylene diphenyl diisocyanate) plant to a 400, 000 tpa plant. The total outlay for the new TDI plant and the capacity addition for MDI in Germany is expected to be around US$423 mln.
